Description
本發明有關於一種胎壓偵測結構及胎壓偵測裝置,尤指一種可達到避免發出的無線訊號受干擾及節省佔用空間的胎壓偵測結構及胎壓偵測裝置。 The invention relates to a tire pressure detection structure and a tire pressure detection device, and more particularly, to a tire pressure detection structure and a tire pressure detection device that can avoid interference of wireless signals sent and save space.
根據統計,發生在高速公路上的交通事故的原因有超過七成是由爆胎所引起的,但卻只有不到一成的駕駛者平時有主動檢查車輛輪胎狀況的習慣,由上述可以看出,車輛輪胎的異常問題一直是所有駕駛人最難預防的問題,因此,業者便開發出一種胎壓偵測裝置以常態偵測輪胎狀況,並於車輛輪胎狀況異常時立刻提醒駕駛人注意,進一步避免事故傷亡發生。 According to statistics, more than 70% of the causes of traffic accidents on highways are caused by flat tires, but less than 10% of drivers usually have the habit of actively checking the condition of vehicle tires, as can be seen from the above. The abnormality of vehicle tires has always been the most difficult problem for all drivers to prevent. Therefore, the industry has developed a tire pressure detection device to detect tire conditions in a normal state and immediately alert the driver when the tire conditions of the vehicle are abnormal. Avoid accidental casualties.
而習知一般胎壓偵測裝置裝設在車輛輪胎的輪框上,該胎壓偵測裝置包含一殼體、一電路板、一胎壓感測器、一發射天線、一處理器及一提供電力的電池所組成,該殼體的底側是貼設在該輪框內的底部上,該電路板(如PCB)容設於該殼體內的底側,該發射天線與處理器及該胎壓感測器一起焊接在同一塊面積大的電路板的一側上,該處理器電性連接該發射天線及該胎壓感測器,且該發射天線與該胎壓感測器是位在相對該電路板一側的同一水平面上,該電池放置在該殼體內的底側且相鄰該電路板,該電池與該電路板位在相對該殼體底側的同一水平面上。 The conventional tire pressure detection device is mounted on a wheel frame of a vehicle tire. The tire pressure detection device includes a casing, a circuit board, a tire pressure sensor, a transmitting antenna, a processor, and a The bottom side of the casing is attached to the bottom inside the wheel frame. The circuit board (such as a PCB) is housed on the bottom side in the casing. The transmitting antenna and the processor and the The tire pressure sensor is soldered together on one side of the same large circuit board. The processor is electrically connected to the transmitting antenna and the tire pressure sensor, and the transmitting antenna and the tire pressure sensor are in place. On the same horizontal plane as the side opposite to the circuit board, the battery is placed on the bottom side in the casing and adjacent to the circuit board, and the battery and the circuit board are located on the same horizontal plane as the bottom side of the casing.
雖習知一般胎壓偵測裝置裝設於該車輛輪胎的輪框上來達到胎壓偵側的效果,但卻延伸出另一問題,就是習知的胎壓偵測裝置的電路板其上的發射天線與胎壓感測器具有方向性,因發射天線與胎壓感測器於電路板是在同一水平面上,使胎壓感測器於安裝上有一定方向性及發射天線也有方向性,以致於導致 受限於胎壓感測器方向性而無法改變發射天線與輪框相對的角度的問題,進而造成收訊不穩定及收訊不佳的狀況發生。另外,由於電路板與電池是在同一水平面上設置的關係,使該殼體需增加多餘空間來裝設電池,導致電池佔用空間的問題;雖另一業者為了改善電池佔用空間的問題,便將電池重疊設於該電路板的背面來達到節省空間,可是此方式卻會造成電池干擾該電路板的正面上設置的發射天線,造成發射天線發送的無線訊號受到干擾,進而導致發送的無線訊號品質不佳及收訊不穩定的問題。 Although the conventional tire pressure detection device is conventionally installed on the wheel frame of the tire of the vehicle to achieve the effect of the tire pressure detection side, another problem is extended. The circuit board of the conventional tire pressure detection device is The transmitting antenna and the tire pressure sensor have directivity. Because the transmitting antenna and the tire pressure sensor are on the same horizontal plane on the circuit board, the tire pressure sensor has a certain directivity on the installation and the transmitting antenna also has directivity. So that Limited by the directivity of the tire pressure sensor, the problem that the relative angle between the transmitting antenna and the wheel frame cannot be changed, resulting in unstable reception and poor reception. In addition, because the circuit board and the battery are arranged on the same horizontal plane, the housing needs to add extra space to install the battery, which causes the problem of battery occupation space. Although another industry operator will improve the problem of battery occupation space, The battery is overlapped on the back of the circuit board to save space. However, this method will cause the battery to interfere with the transmitting antenna on the front of the circuit board, causing interference to the wireless signal sent by the transmitting antenna, which will cause the quality of the wireless signal sent Poor and unstable reception.
再者,由於習知是利用一塊面積大的電路板的同一側上設置有前述發射天線、處理器、胎壓感測器及電池,但因各元件(包含發射天線、處理器、胎壓感測器及電池)的重量不同,且各元件的重心位於電路板的同一側位置的不同區域,使該電路板上的各元件設置位置配重不均勻,使得造成胎壓偵測裝置的重量不平衡,進而容易導致胎壓偵測裝置裝設於車輛輪胎的輪框上運轉時因重量不均勻而產生異音的問題。 Furthermore, since it is conventional to use a large-area circuit board with the aforementioned transmitting antenna, processor, tire pressure sensor, and battery on the same side, the components (including the transmitting antenna, processor, and tire pressure sensor) The weight of each component is different, and the center of gravity of each component is located in a different area on the same side of the circuit board, which makes the positioning weight of each component on the circuit board uneven, which causes the weight of the tire pressure detection device to vary. The balance may easily cause the problem of abnormal sound due to uneven weight when the tire pressure detection device is mounted on a wheel frame of a vehicle tire.
